the difference is that in the document that susan rice basing remarks on she used the term "extremist" instead of al-qaeda. "tremists." that could include a range of people including al-qaeda but, of course, we know that ansar al-sharia in libya has someda. it's not clear they were taking directions from al-qaeda. but the difference between saying specifically we know this was an al-qaeda attack, or extremists. they did not say we know it's al-qaeda there. indications it might be al-qaeda. that is the difference. semantics but to some people it's now the point of great controversy. >> shannon: if we are talking about changing a word, al-qaeda to extremist that thing what about the video? who included that? >> it's not that there was one word change. al-qaeda became extremist. that would be irrelevant. the story she told was a false narrative. it was about a mob inspired by a video. we know, herron reported that the f.b.i. knew two days earlier by asking ones who had been in libya and the ones we evacuated. i mean in the benghazi consulate. we evacuated them. they were on the scene. th
